Just because you and Kaiser were no longer dating, did not mean that any of his jealousy had came to cease.

Having broken up due to his lack of effort in the relationship-- or rather, his extra exertion of effort in his soccer career, you had ended things with a petty argument and a sour taste in your mouth. You had the idea in your head that you two were completely done: that you could move on to other people. However, it seemed that your ex had other plans.

But even though his jealousy was obvious, his pride and ego were too big to admit his faults in your relationship. He was too prideful to admit that he regretted mistreating you.
